ANTIRATTLER FOR WINDOW SASHES Filed Dec. 4, 1945 U INVENTOR ERBACH MARGARET ATTORNEYS Patented Aug. 10, 1948 UNITED STATES PATENT OF ICE ANTIRATTLER. FOR WINDOW SASHES Margaret Erbach, Milwaukee, Wis.

Application December 4, 1945, Serial No. 632,662

1 Claim. 1

This invention appertains to attachments for windows and the like, and more particularly to means for holding a window sash tight in its frame, whereby rattling and shaking thereof during windy weather will be prevented.

fine of the primary objects of my invention is to provide a novel spring member carried by the window sash for movement into and out of wedging engagement with the sash and frame, so that the sash will be held firmly in place.

Another salient object of my invention is to provide an anti-rattling device for Window sashes embodying a resilient bowed body having an attaching foot formed on one end thereof, pivotally mounted upon the sash and an inclined arm on the other end thereof adapted to be wedged between the sash and frame, the arm and bowed body functioning to hold the sash in the frame against rattling.

A further important object of my invention is to provide novel means for forming the body and foot whereby the spring can be conveniently and easily placed upon a headed fastening element such as a screw carried by the sash and readily turned on said sash into and out of operative engagement with the window frame.

A still further object of my invention is to provide an anti-rattling device for window sashes which will be durable and efficient in use, one that will be simple and easy to manufacture and one which can be placed upon the market and applied to a window at a small cost,

With these and other objects in view, the invention consists in the novel construction, arrangemen-t and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawing, in which drawing:

Figure 1 is a fragmentary front elevational view of a window sash and frame showing my novel anti-rattling attachment applied thereto, the attachment being shown in full lines in its operative position and in dotted lines in its swung down inoperative position.

Figure 2 is a detail horizontal sectional view through a portion of a sash and window frame, showing the anti-rattling attachment connected to the sash and in its operative position in full lines.

Figure 3 is a detail fragmentary vertical sectional view through the window sash, illustrating the means of applying the anti-rattling attachment to a fastening element carried by the sash, the attachment being shown in longitudinal section, and

Figure 4 is a perspective view of the attachment removed from the window sash.

Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A generally indicates my anti-rattling attachment for a window W.

The window W forms no part of my invention and can be of any preferred construction. As illustrated, the window includes a frame 5 having side pieces 5 provided with a stop bead I and a parting strip 8 defining a guideway 9 for the sliding sash II]. The sash ll'l can include the side rails ll.

My anti-rattling attachment A comprises a leaf spring formed from any desired resilient metal, and this spring includes a substantially semi-circular arcuately bowed body portion 12. The body portion has formed on its inner end an inturned attaching foot l3. The foot [3 extends substantially radially relative to the axis of the bowed body. The outer end of the body has formed thereon an outwardly extending arm [4. Particular attention is called to the fact that the arm 14 extends at an angle to the attaching foot I3 and at an acute angle relative to the outer face of the sash. The arm 14 is of considerable length for insertion between a rail I l of the sash l0 and the stop bead l.

The attachment is adapted to be pivotally mounted upon one rail ll of the sash and I have provided a novel means for facilitating the mounting of the attachment upon a headed fastening element, such as a screw IS.

The screw I5 is threaded into one rail ll of the sash a desired distance away from the stop bead land the head l6 of the screw is spaced a slight distance from the outer face of the sash. The distance of the head away from the sash must be at least equal to the thickness of the spring attachment A for a purpose which will now be described.

In order to facilitate the quick association of the attachment with the screw, the bowed body I2 and the attaching foot l3 has formed therein a longitudinally extending keyhole slot It. The enlarged 'portion 1 I of the keyhole slot terminates substantially at the central portion of the body l2.

After the screw I5 has been secured to the sash, the bowed body I2 is placed with its outer face against the sash and the head N5 of the screw I5 is inserted in the enlarged portion ll of the slot (see Figure 3). The spring attachment A is now turned in the direction of the arrows in Figure 3 so that the head of the screw will ride on the inner face of the body and the head of the screw will project beyond the opposite side walls of the keyhole slot. The attachment is turned until the screw rides to the inner end of the slot, which terminates in the foot l3. The attachment is now connected to the sash by the foot and the attachment is adapted to be rotated on the screw. If desired, the inner end of the keyhole slot I6 can be slightly enlarged as shown at [8 to facilitate the turning of the attachment on said screw.

In use of my attachment, the same normally depends from the screw and occupies the position shown in dotted lines in Figure 1. When it is desired to bring the attachment into operative position, the same is rotated on the screw and the inclined arm [4 is inserted between the sash and the stop bead l and is wedged between the sash and the stop bead. The attachment is preferably moved to a substantially transverse position across the adjacent rail of the sash. It can be seen that the arm l4, being at an incline to the adjacent faces of the sash and stop bead, will be eflectively wedged between the sash and bead and that, due to the resiliency of the body l2, the arm will be urged toward the stop bead and the foot will press against the sash.

While I have shown my attachment applying to an ordinary window sash, it is to be understood that the same can be used with great effectiveness on the windows of automobiles, airplanes and the like.

Changes in details may be made without de- 4 parting from the spirit or the scope of my invention, but what I claim as new is:

An anti-rattling attachment for a window of the type having a frame and a, sliding sash comprising a resilient leaf spring having an arcuate body, an attaching foot on the inner end of said body, an outwardly extending arm formed on the outer end of the arcuate body arranged at an acute angle to the sash and adapted to be wedged between the sash and the frame, and means for pivotally connecting the foot to the sash, said means for pivotally securing the foot on the sash including a headed fastening element adapted ment.
